RTV Silicone Rubber Additives. Our range of RTV's is quite extensive, but you can continue to modify these rubbers further!

First we have 50cps Silicone Diluent. This is a silicone oil with many uses. You can dilute the rubber making its viscosity less and at the same time softening it. If you intend to dilute, consider starting at a higher shore hardness bfore starting! The side effect of large additions of RTV Silicone Rubber Diluent is Oil Leech. This means during periods of non use the Silicone Rubber will exude oil.  Although useful for some reasons, ecessive addition can reduce tear strength by some margin.

Next, Thixotropic. Have something to copy thats fixed in place? On the ceiling, wall or free standing it matters not, the addition of a Thixtropting Agent to RTV Silicone Rubber will allow moulds to be created in all kinds of scenarios. Added at 2% for full thixotrope properties or 1% for a little easier handling (caution it will slump a little at 1%!) your imagination is the limit to mould construction. ACC Thixotropic is compatible in the 900 series (condensation cure category) and partially compatible with TOMPS Value RTV Silicone Rubber and do not use in any addition cure silicone! If its not in the Value or condensation category then its not compatible. Check back soon for Addition Cure Thixotropic.

Finally we have our Silicone Pigments. We have linked these in two categories (Pigments & RTV Additives) for ease of finding. Added at 5-10% you can colour our stock translucent Condensation Cure RTV Silicone Rubber Black, White, Grey, Light Flesh and Dark Flesh. Available in 25g & 50g kits to suit either addition ratio or kit size. DO NOT USE IN ADDITION CURE SILICONE - you may cause a cure inhibition.
